Configuring STP 7-11
config stpd <stpd_name> delete vlan
[<name> | all]
Allows you to remove one or all VLANs from an STPD. If
all is specified, the association between the STPD and
VLAN is removed, but both still exist.
config stpd <stpd_name> hellotime
<value>
Allows you to specify the time delay (in seconds)
between the transmission of BPDUs from this STPD when
it is the Root Bridge.
The range is 1 through 10. The default setting is 2
seconds.
config stpd <stpd_name> forwarddelay
<value>
Allows you to specify the time (in seconds) that the ports
on this STPD spend in the listening and learning states
when the Switch is the Root Bridge.
The range is 4 through 30. The default setting is 15
seconds.
config stpd <stpd_name> maxage <value> Allows you to specify the maximum age of a BPDU in this
STPD.
The range is 6 through 40. The default setting is 20
seconds.
Note that the time must be greater than, or equal to
2 x (Hello Time + 1) and less than, or equal to
2 x (Forward Delay –1).
config stpd <stpd_name> priority
<value>
Allows you to specify the priority of the STPD. By
changing the priority of the Switch, you can make it more
or less likely to become the Root Bridge.
The range is 0–65,535. The default setting is 32,768. A
setting of 0 indicates the highest priority.
config stpd <stpd_name> port cost
<value> <portlist>
Allows you to specify the path cost of the port in this
STPD.
The range is 1–65,535. The Switch automatically assigns a
default path cost based on the speed of the port, as
follows:
■ For a 10Mbps port, the default cost is 100.
■ For a 100Mbps port, the default cost is 19.
■ For a 1000Mbps port, the default cost is 4.
config stpd <stpd_name> port priority
<value> <portlist>
Allows you to specify the priority of the port in this STPD.
By changing the priority of the port, you can make it
more or less likely to become the Root Port.
The range is 0–255. The default setting is 128. A setting
of 0 indicates the lowest priority.
